Solution Overview

Problem

Existing siphon apparatuses for water softeners often result in splashing and backflow of waste fluid, contaminating the soft water and reducing the efficiency of the water softening process.

Innovation Solution

A siphon apparatus with an inner funnel featuring a meshed member, such as a pattern of radially extending trapezoids, is used to stabilize and direct the flow of fluid, eliminating splashing and backflow by incorporating an air gap and ensuring a sealed connection through the use of an O-ring seal and modular construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional siphon is used for waste removal, then waste fluid can be discharged from the water softener, but splashing and backflow occur contaminating the soft water

Engineering Contradiction:
Improveprevention of soft water contaminationVSAvoidsplashing and backflow of waste fluid
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary air gap between the siphon outlet and the soft water storage area. This air gap acts as a physical barrier that prevents direct contact between waste fluid and soft water, thereby eliminating the contamination risk while allowing waste discharge to continue

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the harmful backflow and splashing elements by designing a siphon system where waste fluid is separated from the soft water pathway. The siphon outlet is positioned and configured to discharge waste away from the soft water storage area, removing the contamination source from the system

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the siphon is connected directly to the water softener outlet, then waste removal is efficient, but backflow can occur from the sewer through the siphon

Engineering Contradiction:
Improvewaste removal efficiencyVSAvoidprevention of backflow contamination
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The air gap serves as an intermediary barrier that maintains one-way flow. It allows waste to be efficiently discharged through the siphon while preventing any reverse flow from the sewer, as the air gap breaks the siphon effect that would otherwise allow backflow

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The design incorporates preliminary anti-action by positioning the siphon outlet and air gap to preemptively prevent backflow before it can occur. The air gap is strategically placed to counteract any potential siphon-driven reverse flow from the sewer connection

Inventive Principle:
Principle #9Preliminary anti-action
